Description

Now that Ruby 1.9 has Complex as a builtin type, it would be interesting if Matrix provided the following instance methods:
#conj, alias conjugate
#imag, alias imaginary
#real, 
#real?, 
#rect, alias rectangular

Corresponding patch attached.

This patch could also be part of mathn in the ruby 1.8 branch.
